Further, the clamp is circular in cross section and is divided into two parts, and the two parts are fixed into a whole through a third bolt.
Further, the longitudinal sealing plate is fixed on the top surface of the sealing base through a second bolt.
Furthermore, the sealing base, the longitudinal sealing plate, the transverse sealing plate, the longitudinal sealing ring and the transverse sealing ring are formed by splicing two parts.
Further, the second groove is provided with two channels.
The utility model has the technical effects that: the vertical sealing seat is arranged on the vertical side surface of the vertical pipe, the vertical sealing seat is fixedly pressed by the vertical sealing plate and the horizontal sealing plate, then the vertical sealing seat is fixed on the top surface of the vertical pipe channel through a first bolt, the vertical sealing seat can be ensured to be transversely and longitudinally sealed, the clamping clamp is positioned in a third groove of the vertical pipe, and the bottom surface is pressed against a boss of the vertical pipe channel.

Detailed Description
The present utility model will be further described with reference to the accompanying drawings and specific examples, which are not intended to limit the utility model, so that those skilled in the art may better understand the utility model and practice it.
The embodiment of the utility model discloses a movable suspension sealing device for a flexible vertical pipe, which comprises a sealing base 1, a longitudinal sealing plate 2, a transverse sealing plate 3, a longitudinal sealing ring 4, a transverse sealing ring 5 and a clamping clamp 6, as shown in fig. 1-5.
The sealing base 1 is provided with a longitudinal side surface and a bottom surface with circular cross sections, a first groove 7 is formed in the longitudinal side surface, the longitudinal sealing ring 4 is arranged in the first groove 7, and the longitudinal sealing plate 2 compresses the longitudinal sealing ring 4 in the first groove 7. The bottom surface is provided with a second groove 8, the transverse sealing ring 5 is arranged in the second groove 8, and the first bolt sequentially penetrates through the transverse sealing plate 3 and the sealing base 1 to tightly press the transverse sealing ring 5 on the top surface of the vertical pipe channel 9.
The holding clamp 6 is sleeved on the periphery of the vertical pipe and is clamped in a third groove of the vertical pipe, and the bottom surface of the holding clamp 6 is pressed against a boss of the vertical pipe channel 9.
The holding clamp 6 is circular in cross section and is divided into two parts, and the two parts are fixed into a whole through a third bolt. When the novel anti-theft lock is installed, the two parts are detached and then sleeved on the periphery of the third groove, and are locked through the third bolt.
The longitudinal sealing plate 2 is fixed on the top surface of the sealing base 1 through a second bolt, and the longitudinal sealing ring 4 can be pressed tightly, so that the tightness of the vertical pipe and the side wall of the vertical pipe is ensured.
The sealing base 1, the longitudinal sealing plate 2, the transverse sealing plate 3, the longitudinal sealing ring 4 and the transverse sealing ring 5 are formed by splicing two parts.
The second grooves 8 are provided with two channels, and a transverse sealing ring 5 is arranged in each channel of the second grooves 8.
The working process of the utility model when in use is as follows: the end part of the vertical pipe is lifted to the upper part of the vertical pipe channel 9, two parts of the holding clamp 6 are sleeved in the third groove and locked by the third bolt, and the vertical pipe is lowered until the bottom surface of the holding clamp 6 is pressed against the boss of the vertical pipe channel 9; then the transverse sealing ring 5 is installed in the second groove 8, and the transverse sealing plate 3 and the sealing base 1 are sequentially penetrated through by using a first bolt, and are fixed to the top of the vertical pipe channel 9; and then the longitudinal sealing ring 4 is installed in the first groove 7, and the longitudinal sealing plate 2 is blocked in the sealing base 1 by using the second bolt, so that the longitudinal sealing ring 4 can be pressed tightly. When the vertical pipe needs to move axially, the vertical pipe can be lifted longitudinally by disassembling the sealing base 1, the longitudinal sealing plate 2, the transverse sealing plate 3, the longitudinal sealing ring 4 and the transverse sealing ring 5, so that the butt joint of the flanges is realized.
The above-described embodiments are merely preferred embodiments for fully explaining the present utility model, and the scope of the present utility model is not limited thereto. Equivalent substitutions and modifications will occur to those skilled in the art based on the present utility model, and are intended to be within the scope of the present utility model.
